Section B. Compelling persons to serve in the forces of a hostile power
South Africa’s LOAC Manual (1996) states that “compelling a protected person to serve in the forces of the hostile power” is a grave breach of the 1949 Geneva Conventions.
South Africa’s ICC Act (2002) reproduces the war crimes listed in the 1998 ICC Statute, including in international armed conflicts: “compelling a prisoner of war or other protected person to serve in the forces of a hostile Power” and “compelling the nationals of the hostile party to take part in the operations of war directed against their own country, even if they were in the belligerent's service before the commencement of the war”.
South Africa’s Implementation of the Geneva Conventions Act (2012) states: “A protected prisoner of war who is in the custody of the South African National Defence Force must be granted the protection of the  Third [Geneva] Convention or the  Fourth [Geneva] Convention, as the case may be.”
The Act defines a “protected prisoner of war” as a “person protected by the Third Convention or a person who is protected as a prisoner of war under [the 1977 Additional] Protocol I”.
The Act also states:
5. Breach of Conventions and penalties
